ops sorry i meant 980N.

k well fg1 = 980 N , we have r1 = 128,000, what will be r2?

I need to find the weight at of the object at each distance using the ratio that you stated.

Homework Statement For this problem, use ratios only to obtain the weight of a person at the following distances. Assume the person weighs 980N on the surface of Earth. a) 128 000km above the surface of Earth b) 4.5 times the distance from the centre of Earth c) 745 400km from Earths...

got it. thank you

yeah i just noticed awhile ago...so do i just sub them all the info and isolate the variable of the tank?

Homework Statement Two tankers of equal mass attract each other with a force of 3.5 x 10(to the power of 3)N. If their centres are 85m apart, what is the mass of each tanker? mass of 2 tankers = ? F= 3.5 x 10(to the power of 3)N r= 85m G = 6.67 x 10(to the power of -11)...

Homework Statement The question is: What is the distance between the moon and the Earth if the mass of the moon is 7.34 x 10(to the power of 22) kg and the force of attraction between the two is 2.00 x 10(to the power of 20) N? Mass of the moon = 7.34 x 10(to the power of 22) kg...
